技术领域 FIELD

[0001]本发明涉及X射线机技术领域,特别是涉及一种X射线机及其C型臂旋转机构。 [0001] Technical Field The present invention relates to an X-ray machine, and more particularly to an X-ray machine and the C-arm rotating mechanism.

[0002]装载有C型臂的X射线机在医疗器械领域得到广泛的应用,大部分该类X射线机的C型臂可沿水平轴旋转,且旋转角度不小于±180°。 [0002] loaded with an X-ray C-arm machine is widely used in the field of medical devices, most of the class C-arm X-ray machine is rotatable along a horizontal axis, and the rotation angle of not less than ± 180 °. 若X射线机对C型臂沿水平轴旋转角度范围不加以限制,当C臂旋转角度过大时,容易造成导线缠绕在机器上。 If the X-ray machine is not to limit the C-arm along a horizontal axis rotation angle range, when the rotational angle of the C-arm is too large, it is likely to cause wire wound around the machine.

[0003] X射线机的探测器和X射线管通过导线连接到控制电路部分,为避免导线缠绕,需要安装限位器对C型臂的旋转角度范围加以限制。 [0003] X-ray machine and the X-ray detector tube is connected to the control circuit via a wire section, the wire winding to avoid the need to install the stopper to limit the rotational angle range C-arm. 目前用于C型臂的旋转限位器一般是通过挡块与挡块的接触限位或者是设置轻触开关,通过电路控制限位。 Currently used for the C-arm rotation limit stopper typically by contact with stopper or stopper is provided touch switch, by limiting the control circuit. 这些限位器的结构确定之后,C型臂的旋转角度范围是确定值,调节困难。 After determining the structure of the stopper, the C-arm rotation angle range determination value is difficult to adjust.

[0004]所以,对于传统的限制C型臂旋转角度范围的X射线机来说,由于其结构上的限制,一旦确定限位器结构,C型臂旋转角度范围将难以调节,使得X射线机使用不够灵活,无法满足日常医疗的需求。 [0004] Therefore, with the conventional C-arm to limit the range of rotational angle X-ray machine, because its structural limitations, once the stopper structure, the C-arm rotation angle adjustment range will be difficult, so that the X-ray machine use not flexible enough to meet the needs of everyday medical care.
